n Application filed November 18,1902.. Serial No. 131,828.

i' county and State of New York, have invented a certain new' and usefulImprovement in Street-Cleaners, of which the following is aspecification. i

My invention relates' to.' animprovcment in street sweepersl and likedevices andthe object is to provide .an improved apparatus of this kindthat will remove the dirt or snow from the street anddeposit it in aVehicle or intobags for transportation.

The invention is more clearly set forth in the followpanying drawings,in Vwhich Figure l shows a side view of my sweeper; Fig. 2 showsapartial longitudinal section of Fig. l; and Fig.- 3, is a view partlyin section and partly in elevation illustrating'a detail of theinvention.

4 In the drawings A,-denotes the conveyer casing.

provided with sprocket wheels R, R. Engaging the v wheels R, R, are theendless chains P, which carry i blades or shovels projectingfthereromonen incline.`

Mountedupon- `the -hub of one ofthe lwheels of the.

vehicle and fix'edly secured thereon'is a gearwheel D, which mesheswitha gear wheel E fixedly mounted on'a shaft carrying a `sprocket wheel'E'. A sprocket chain' F meshes with: sprocket wheel E and with a'nfother sprocketv wheel G'which is -ixedly mounted on 'the outer end ofthe s haft .O,'which shaft also has iixedly mounted on it the sprocketwheel R inside the chute. This vshaft also -carries a sprocket wheel-Hwhich carries a'sprocket-chain I which meshes with a l sprocket wheelJtixedly mounted ontheshaft carrying the brush. This chain 4ofgearingasaforesaidis vpref- .erablyi so'Iarranged-that the speedof thebrush i's` vgreater than thatv of theshaft O andthe speedof the shaft Ois greater than that ofthe wheel ofthe vehicleA I 4 cleansing the stime,and mechanism for 'operating the brush towhich it is geared..V

The npper part VorA roof ofthe chute neariits' lower en'd isl jointed'bya hinge joint at A/ j'stabove ,thebrush and this jointedtpbrtin A7 whichsurroiindsthe back also. carriesteethz whiehjeeth are adspt'edto rest Bisthe supporting frame for carrying my sweeper and its various partis.This frame is mounted on wheels on the bristles of the brush to cleanit.'A The'sliaft L which carries the brush is mounted in guideways K soas to permit of vertical movement due to the un.- evenness' of theground being traveled over.

Atthe upperl end' of the chute there `is au elbow l formed and 'on thiselbow issecured a iicxiblcV spout or chute S 'of `any suitable materialand length. This Vto have aropeoi= other suitable material attached toit so as to. control its movement and. distribute the refusoaround thevehicle in which it is being deposited.;

The 'casing is somounted that'it'c'an be readily tilted' to the positionshdwn'or can Ibe made parallel with the fram', Bwhich lcarries it asVdesired by meansof the pinion V which is operated by the handle Vf andmeshes with the toothed rack U.

I provide rollers P loosely mounted in the side o f" the casing A onwhich the endless belt carrying the blades Q Q rest so as to hold theblades'Q Q in contact Awith the platform'A. 5

The operation of my improved sweeper is as follows.

the wheel upon which isiixedly mounted thegear wheel D which in turnrevolves gear E and sprocket wheel E, sprocket wheel G through chain F;Sprocket sprocket R revolves wheel R and sets the blades Q Q" intooperation. Shaft O also revolves sprocket H mounted thereon and this invturn throughehain I re.' volves'slprocket J and brush M. When theapparatus is in 'operation the brush Mwhich isfmade of any suit ablematerial-revolves rapidly and throws dirt, snow duc; uponto thecasingwhere theshovels or' blades Q sweep it or push itupthe casing tillit'reaches the' el Vbow A5 whereit drops into the flexible spoutorchutel and is emptied into and V'distributed around anydcs'irablevehicle; V
